Keyboard backlight not working on ASUS laptop

Hello everyone. ASUS recently bought a laptop. There is such a feature as keyboard backlighting. The thing is not only cool, but sometimes useful, especially at night. And now, a couple of days ago, this function disappeared. Question for Connoisseurs: what to do in this case?

Depending on the model, this feature is enabled and controlled by the function keys on the keyboard. Examine F3 and F4 for a special luminance symbol. It is necessary to hold down the Fn button and press F4 several times to increase the brightness of the backlight, and to decrease FnF3. You can completely turn on or off the backlight by a combination of Fn and Space (space).

As I understand it, you have a warranty laptop, since you recently bought it. Maybe it’s time to contact the authorized Asus service? The problem, of course, is not of this level, most likely, but the hardware part itself should definitely not be interfered with. I mean, a screwdriver in hand and forward. At least you can lose the guarantee.

Most likely, you will need to reinstall or install the ATKACPI driver and hotkey-related utilities. You need to download it from the official ASUS website in the “Drivers and Utilities” section indicating the laptop model and operating system version. It happens that the latest driver version is not suitable for a specific computer configuration. Then try to install the previous release, having previously uninstalled the current driver through the “Device Manager”. Be sure to reboot after installing the PC. If the problem was in the wood, then everything will work. Here is the link:

Thank! I reinstalled the drivers and it worked! Probably because of the Windows update, the backlight did not work, maybe of course not for this reason, but the main thing is that it works))

I had the same problem on ASUS R556QG. The Fn button works, I adjust the sound with it. But all the other combinations fail, neither F3 and F4, nor Space. Reinstalling the driver didn’t help either. In short, the up-down arrow helped by the popular poke method. turns off / turns on the backlight.

I doubt that something happened to the hardware in your case. If any function is no longer regulated by hot keys, then there may be something with the matrix itself or the loop. But the laptop is new. Although, you can pour or drop it with tea on the first day. There was nothing like that? If the settings or through reinstalling the driver does not fix the problem, it is best to contact the service.

I ran into a canoe where the backlight is on and the brightness is adjusted, but its color is constantly changing. Or only blue is constantly on and I cannot change it. There is not a word about this on Asus’s website, there is nothing in the instructions for the laptop either. Who faced this, tell me how to solve?

I give free advice on adjusting the backlight color. This cannot be achieved with the built-in laptop tools. There are special utilities that will help. Open the ASUS official website (I don’t understand why you could not find it there), enter your laptop model and go to the list of drivers. “Driver Utility”. Find and download the dedicated Armory Crate lighting control service. After installation, you will be able to adjust the brightness and color of the keyboard backlight. The interface is very friendly, completely Russified. Enjoy the effects!

There are also programs Aura Sync or TUF Aura Core. They are selected depending on the laptop model. Look at the sticker on the case: if there is a colored circle with the inscription ASUS AURA RGB. select the TUF Aura Core program, if the inscription ASUS AURA SYNC. then the Aura Sync utility. Note that TUF Aura Core only adjusts brightness, color cannot be adjusted. And further. Don’t be greedy and don’t install multiple programs at once. A lot in this case does not mean good, a conflict of applications is possible.
